UNITED sTATEs JONATHAN W. WARD, OF LARUE, OHIO.

ADJUSTABLE HOLDBAGK.

Specification of Letters Patent.

Application filed October 5, 1908. Serial No. 456,201.

' To all whom it may concern:

Be it known that I, JONATHAN W. WARD, a citizen of the United States, residing at Larue, in the county of Marion and State of Ohio, have invented certain new and useful Improvements in Adjustable Holdbacks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to adjustable holdbacks, and has for its object the production of a simple device for securing the holdback straps to a shaft provided with looking mechanism and a guide for the locking mechanism adapted to be secured longitudinally on the shaft.

One of the objects of the invention is the production of a simple adjustable holdback comprising a minimum number of parts and a simple spring-controlled locking device.

With these and other objects in view, the invention consists of certain novel features of, construction, combination and arrangement of parts as will be described and particularly pointed out in the appended claims, and in the accompanying drawing, in which Figure 1 is a perspective view of my adjustable holdback; Fig. 2 is a side elevation of a locking device; Fig. 3 is a longitudinal sectional view thereof; and Fig. 4. is a plan view of the locking device.

In the accompanyin drawings, 1 denotes a shaft formed with ob ong openings, 2, and provided with a guide-way, 3, having corresponding openings formed therein. The guide-way, 3, is formed with flanges, 4, which are adapted to receive extensions, 5, formed on a supporting member, 6. The supporting member, 6, is provided with upstanding ears, 7, through which a pivot 8 extends. A block, 9, having a reduced end, 10, is mounted on the pivot, 8, and is provided with an obliquely disposed locking pin, 11, which is adapted to enter the oblong openings, 2, said pin being formed on the block, 9, on the end opposite to the point Where said block is pivoted to the ears, 7. A longitudinal slot, 12, is formed in the block, 9, for the purpose of securing a holdback strap thereon. The supporting member, 6, is provided with a flat spring, 13, which is riveted thereto and extends in angular relation from the base of said supporting member and bears against the rear end of the block, 9. The strap-receiving block, 9, is adjusted on the shaft 1 by raising the pin 11 out of the openings, 2, and moving the extensions, 5, on the guide way, 3. My improved holdback can therefore be quickly adjusted by the use of one hand.

From the foregoing description, taken in connection with the accompanying drawing, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters-Patent, is:

1. A holdback comprising a tongue provided with a flanged guide way, a supporting member formed with lateral extensions slidable on the guideway and formed with upstanding cars, a strap receiving block formed with a locking pin and ivoted to the ears, and a spring secured to tie supporting member and adapted to bear against the rear end of the strap-receiving block.

2. A holdback comprising a shaft formed with a flanged guide Way and provided with oblong openings, a supporting member formed with lateral extensions and u standing ears slidable on the guide way, a ocking block formed with an obliquely disposed pin and a reduced end pivoted to the upstanding ears, and a spring secured to the supporting member and ada ted to exert tension against the under sideo thereduced end of the block.

3. A holdback comprising a shaft formed with oblong openings regularly s aced a art, a supporting member formed wit latera ex tensions and u standing ears slidable on the guide way, a b ock having a reduced end and a longitudinal body slot and provided with an obliquely disposed pin pivotally supported on the upstanding ears, and a spring secured to the supporting member and arranged to exert tension against the under side of the reduced end of the block.

4. An adjustable holdback comprising a shaft formed with longitudinallyspaced oblong openings and provided with a flanged guide Way, a support formed with lateral extensions slidable m the guide way and formed with upstanding supportin cars, a locking block having a longitudina slot for the re- Patented Jan. 5, 1909. it
